Festo VBNF series check valves with a piloted non-return function and a manual exhaust function. The piloted non-return function can be used for a intermediate stop. If a pilot signal is applied, the exhaust air can escape. If no pilot signal is applied, the valve shuts off the exhaust air from the drive and the drive stops temporarily. The integrated manual exhaust function can be used to manually vent a pneumatic drive.
